Abstract
Introduction and aim: Fatigue of injury-prone athletes and their placement in situations such as performing shear maneuvers increases the risk of anterior cruciate ligament injury. Therefore, this research aims to answer the question, does functional fatigue change the effect of neuromuscular training on kinetic variables during cutting in injury-prone male athletes?
Methodology: The current research is semi-experimental and was carried out in two control and experimental groups as a pre-test and post-test design with and without fatigue before and after neuromuscular exercises. 32 males student-athletes aged 18 to 25 with trunk control defects were purposefully selected and randomly placed in the control group (16 people) and the experimental group (16 people). The force plane was used to measure ground reaction forces. Analysis of variance test was used for statistical analysis at a level smaller than P<0.05.
Results: The results of the present study showed a significant improvement in ground reaction force variables in the post-test of the experimental group compared to the pre-test (P<0.05). While none of these variables had significant changes in the control group (P>0.05).
Conclusion: It seems that doing trunk and hip neuromuscular training in athletes with a trunk control defect leads to a significant improvement in the stability of the trunk control, so in the conditions with and without fatigue, they were able to show a significant improvement in the selected parameters of the ground reaction forces. Therefore, this training method can probably be recommended as a beneficial method for athletes and the mentioned conditions

Abstract
The aim of this research was effect of eight weeks of neuromuscular training (NMT) with and without cognitive-dual tasks (DTs) on proprioception and balance of athletes with ACL deficiency (ACL-D). 39 soccer players with ACL-D were selected purposefully and randomly divided into three groups of 13 (control group, neuromuscular training group and neuromuscular training with dual tasks group). Two training groups performed the exercises for eight weeks and three sessions per week. cognitive-motor dual tasks were performed in one of the groups along with neuromuscular exercises in the form of counting down numbers, memorizing numbers, calculating unexpected equations, specialized football skill movements. The results of the current study indicated that there was no significant difference in knee joint proprioception in the open and closed kinetic chain after applying the intervention between the three groups, but there was a significant difference in lower extremity performance of the athletes based on the Y balance test in the anterior and posterior-lateral direction between the three groups (p<0.05). It seems that providing neuromuscular exercises along with cognitive-dual tasks can probably be considered as a useful approach to improve lower extremity performance based on the Y balance test in athletes with anterior cruciate ligament deficiency.
